The Optimum Temperature For The Growth Of Tea Trees

2022-07-23 15:33:47

In essence, tea planting is still a traditional agricultural activity, which is greatly affected by environmental factors. Among all environmental factors, temperature has a relatively large influence on the quality of tea leaves. The temperature limits the growth rate of tea trees and affects the yield and quality of tea leaves. Of course, in addition to being affected by changes in solar radiation, the temperature is also affected by other environmental factors such as latitude, altitude, slope, and orientation for the entire tea garden.

1. The most suitable temperature for the growth and development of tea trees

In China, there are more than 20 provinces and more than 1,000 counties and cities where tea trees are grown. In the specific division of the four existing tea areas, the temperature of each place is not exactly the same, so it also leads to great differences in the quality of tea. According to scientific research, the most suitable temperature for the growth of tea tree shoots is actually between 20 and 25 degrees. When the temperature is higher than 25 degrees, or when the temperature is lower than 20 degrees, the growth of new shoots will be slower.

Of course, if other ecological conditions are better, this suitable temperature range can still be slightly expanded. For example, when the temperature is higher than 16 degrees, the growth rate of tea trees will continue to increase as the temperature rises. When the temperature is significantly higher than 30 degrees, the temperature of the new shoots of tea trees will drop significantly. When the temperature exceeds the optimum range during the entire growth period of the tea tree, the quality of tea picking will decline. This is why we say that the quality of spring tea and autumn tea is relatively high, especially spring tea, while the quality of summer tea is low, because summer tea is in the hottest season of the year, and the average temperature basically exceeds 30 degree, so the quality is the worst.
